When you are a consultant, you provide advice, predominantly in verbal and written form. So when you are restricted in your ability to operate in either of those capacities, completing work and delivering to clients becomes a challenge.
When I was at Deloitte, the star of my team, who was halfway through a major internal process audit, injured his hand rock-climbing and it threw everyone into a spin because he couldn't type or hold a pen!
I've had a similar experience due to contracting laryngitis at a time when client meetings and workshops meant that I was called on to do a lot of talking.
It got me thinking about when you are in business and core resources are not available or withdrawn for any reason. It's important to have a "plan B" and at least to have thought about a plan of action should you be caught short. I've mentioned business continuity planning in the context of disasters and major interruptions before, but they also should cover the identification of core processes, resources and deliverables and how you would deal with short-term interruptions.
So, with my voice sounding like a cross between Barry White and Mickey Mouse, I needed to determine how I would cope in this situation. Unlike a business continuity plan, which should be well thought of and clearly documented, I had no plan for the "vocal interruption" - I should have. The resulting events show why we all should consider what are the essential elements of our business(es) and have a plan.
